Reliable equipment – Useful and ecological end product

Huge reduction of inconveniences to the neighborhood due to transport noise and dust

Economical and ecological replacement option to landfills

Net GHG reduction when producing fertilizing biosolids

Superior results

“The La Pinière wastewater treatment plant in Laval, dewaters and dries, on an average day, around 30 metric tons of municipal sludge (dry basis) from an average solids content of about 28% at the drying system inlet to a solids content of more than 92% at the outlet. The biosolids produced in this process are certified as BNQ* Grade in the Province of Quebec. A part of these biosolids is distributed as fertilizers and a larger part is currently used as an efficient combustible and process addition in a cement plant in the region. This drying system was rated by Berlie Technologies Inc. for a nominal evaporative capacity of 5 metric tons per hour and processes sludge for an estimated population of 280,000 people.” – Citation from the management

* BNQ Grade is an equivalent, in the Province of Quebec, to the United States EPA-503 Process to Further Reduce Pathogens grade known as Class A Biosolids

Series 1.0, 2.0, 3.0, 4.0, 5.0 & 6.0

Worldwide references

There are 48 references of plants operating with this technology around the world.

Advanced technology

In our Patented Closed-Loop Design, oxygen is replaced by recycled steam in the dryer drum, which eliminates process risks and improves drying efficiency.

Energy savings and recovery

When processing dewatered primary sludge, this drying system can be operated without the purchase of fossil fuels if its end product is recycled on site as an efficient heat source.

When processing dewatered digested sludge from anaerobic digestion, this drying system can be operated without the purchase of fossil fuels if the digestion biogas is recycled as an efficient heat source.
